Risks to the public in computers and related systems

We build new RSA-based encryption schemes secure against adaptive chosen-ciphertext attack (CCA-secure) without random oracles. To do this, we first define a new general RSA-related assumption, the Oracle RSA-type assumption, and give two specific ...

Individuals and organizations who own or use computers in daily operations face many exposures to the risk of loss of hardware, software, and other computing assets, including liability arising from computing operations. Many loss prevention techniques ...

It is a maxim of sound computer-security practice that a cryptographic key should have only a single use. For example, an RSA key pair should be used only for public-key encryption or only for digital signatures, and not for both.In this paper we show ...
